WebXash

WebXash is a front end by x8bitrain for webxash3d-fwgs, a WebAssembly build of the Xash3D FWGS engine. It runs Half-Life and Counter-Strike 1.6 in the browser. The original Half-Life is a first-person shooter developed by Valve, released for Windows on November 19, 1998.

How to play

1. Choose Open game Folder and pick your Half-Life folder, the one that contains valve. The page then lists the games you can launch.
2. Or choose Open ZIP and pick a zip of your valve folder.
3. For a mod such as Opposing Force or Blue Shift, keep its folder next to valve and set a launch option such as -game bshift before you choose the folder.

Play with a keyboard and mouse. Use fullscreen, because Ctrl+W (crouch jump) tries to close the tab in most browsers.

What you need

Your own Half-Life files, and a keyboard and mouse. The page can also play zipped demos. The project says it does not work well on mobile.

Good to know

• The folder is only read. Its files are copied into memory for the session.
• A save manager keeps saves in your browser's storage and can download them. It is off when Counter-Strike 1.6 is selected.
• Multiplayer needs a separate server from the webxash3d-fwgs project.
• Mods that the Xash3D engine does not support probably will not work.
